interactive slide show of solar system, including comets and asteroids.

Summary

Prior to class, teachers had discussed the solar system bodies with the
students and the students and drawn cards of each planet plus a comet and
asteroid. Inside, the scale models of the planets were introduced, using
a scale that made Earth the size of a kumquat. Outside, the students held
their planet cards and were placed on the playground to showing the relative
distance between planets. A third demonstration was to use pre-cut lengths
of string to represent the distance from the sun to the inner planets, with
students holding on to the strings and revolving about the sun.
